  mediasoup:ERROR:Worker (stderr) terminate called after throwing an instance of 'std::regex_error' +0ms
  mediasoup:ERROR:Worker (stderr)   what():  regex_error +0ms

This isn't good, not sure where it comes from exactly though, probably caused by bad input somewhere?

It should not happen with the demo since we control the value we pass to the worker. Said that I've seen regex similar issues in the past due to gcc version but AFAIR we already verify gcc version and require it to be higher than some value.

Thank you for your reply

How should I solve this problem

Seems to be same as https://github.com/versatica/mediasoup/issues/391. Please take a look to it.
